Good, this should also reduce the flood of boring weekly posts like "payment received, TY BitMixer"!
It seems it's already working, indeed.

I think it will reduce the amount of such posts indeed. However, I think it's still gentle to thank BitMixer for the payment. He/she spends money on you in the end, and if you're polite, you should thank someone for that.
